vTiger Custom Field Validation beforesave - php

Question

I have created a custom module on vTiger 6.5.
I have made an event handler for the module but I am wondering how I could perform some sort of validation on this field. So fat I have done this but I am unable to get it work, I have tested the handler just echoing a sting and it works fine.
Please see my code below. Thanks!

Answer 1

After doing some searching around and looking at other peoples event handlers I managed to solve this by changing:
if($eventName == 'vtiger.entity.beforesave') {
if('currentamount' > 20000){
echo "Please go back and enter less than 20000";
exit;
}
to
if($eventName == 'vtiger.entity.beforesave') {
$price = $entityData->get('currentamount');
if($price > 20000){
echo "Please go back and enter less than 20000";
exit;
}
Now I want to see if I can display the message and then give a link to go back to the entity module with all the fields still full.

In my opinion you should use the recordPreSave function.
It's allow you to display an information/error message before to save data on the database
Here is an example:
In your Edit.js:
donCache : {},
checkDon : function(details) {
// alert("checkOverlap");
var aDeferred = jQuery.Deferred();
var params = {
'module' : 'Affectations',
'action' : "checkAffectAmount",
'mode': 'CtrlAffectAmount',
'recordId' : details.don,
'montant' : details.montant
}
AppConnector.request(params).then(
function(data) {
if (data.success == true) {
// console.log(data.result);
var statut = data.result.statut;
var reste = data.result.reste;
if(statut == "error"){
aDeferred.reject(data);
}else {
aDeferred.resolve(data);
}
}
},
function(error,err){
aDeferred.reject();
}
);
return aDeferred.promise();
},
registerRecordPreSaveEvent : function(form) {
var thisInstance = this;
if (typeof form == 'undefined') {
form = this.getForm();
}
form.on(Vtiger_Edit_Js.recordPreSave, function(e, data) {
var check = false;
var recordId = jQuery('input[name="record"]').val();
if (!recordId || recordId) {
var montant_affectation = jQuery("input[name='affectations_montant']").val();
var don_id = jQuery("input[name='affectations_potentialid']").val();
var params = {};
if (!(check in thisInstance.donCache)) {
thisInstance.checkDon({
'montant' : montant_affectation,
'don': don_id
}).then(
function(data){
thisInstance.donCache[check] = data['success'];
form.submit();
},
function(data, err){
thisInstance.donCache[check] = data['success'];
var reste = data.result.reste;
var msg = app.vtranslate("<strong>Attention!</strong> La somme des affectations est supérieure de ")+ reste +app.vtranslate(" Euros au montant du don");
Vtiger_Helper_Js.showPnotify(msg);
delete thisInstance.donCache[check];
}
);
} else {
delete thisInstance.donCache[check];
return true;
}
e.preventDefault();
}
})
},
The PHP part in modules/isa/actions:
<?php
/***********************************
** DEBUT ALTAIR - JPR 15/06/2016 ***
***********************************/
class Affectations_checkAffectAmount_Action extends Vtiger_Action_Controller {
function __construct() {
$this->exposeMethod('CtrlAffectAmount');
}
public function checkPermission(Vtiger_Request $request) {
$moduleName = $request->getModule();
$moduleModel = Vtiger_Module_Model::getInstance($moduleName);
$userPrivilegesModel = Users_Privileges_Model::getCurrentUserPrivilegesModel();
$permission = $userPrivilegesModel->hasModulePermission($moduleModel->getId());
if(!$permission) {
throw new AppException('LBL_PERMISSION_DENIED');
}
}
public function process(Vtiger_Request $request) {
$mode = $request->getMode();
if(!empty($mode) && $this->isMethodExposed($mode)) {
$this->invokeExposedMethod($mode, $request);
return;
}
}
function CtrlAffectAmount(Vtiger_Request $request){
global $adb,$log;
$log->debug("ALTAIR CtrlAffectAmount OK");
$recordId = $request->get('recordId');
$montant = $request->get('montant');
// $query = $adb->pquery("SELECT SUM(unit_price) AS sommeaffectation FROM vtiger_products INNER JOIN vtiger_crmentity ON vtiger_products.productid = vtiger_crmentity.crmid WHERE don_affecte = ? AND vtiger_crmentity.deleted=0",array($recordId));
$query = $adb->pquery("SELECT SUM(affectations_montant) AS sommeaffectation FROM vtiger_affectations INNER JOIN vtiger_crmentity ON vtiger_affectations.affectationsid = vtiger_crmentity.crmid WHERE vtiger_affectations.affectations_potentialid = ? AND vtiger_crmentity.deleted=0",array($recordId));
$sommeAffectation = $adb->query_result($query,0,"sommeaffectation");
$query = $adb->pquery("SELECT amount FROM vtiger_potential INNER JOIN vtiger_crmentity ON vtiger_potential.potentialid = vtiger_crmentity.crmid WHERE potentialid = ? AND vtiger_crmentity.deleted = 0", array($recordId));
$montantDon = $adb->query_result($query,0,"amount");
if ( ($sommeAffectation + $montant) == $montantDon) {
$statut = "ok";
$reste = "";
} else if( ($sommeAffectation + $montant) > $montantDon) {
$statut = "error";
$reste = ($sommeAffectation + $montant) - $montantDon;
}
$value = array('statut'=>$statut, 'reste'=>$reste);
$response = new Vtiger_Response();
$response->setEmitType(Vtiger_Response::$EMIT_JSON);
$response->setResult($value);
$response->emit();
}
}

Oh. you have 1 invalid error here. please change:
if($eventName == 'vtiger.entity.beforesave') {
$currentAmount = $entityData->get('currentamount');
if($currentAmount > 20000){
echo "Please go back and enter less than 20000";
exit;
}
}
